Voltaic — Integrated Concrete Solar Roof Tile
Voltaic is not a panel system added on top of a roof. It is an architectural concrete tile with the photovoltaic cell cast directly into the material during manufacturing. The tile is the roof. From the street, from the air, from every architectural view, it reads as a beautifully designed roof and nothing else. No visible hardware. No rack system. No indication that anything other than an exceptional roof is present.
Manufactured by Westlake Royal Building Products, one of North America's most established roofing material manufacturers with over a century of concrete tile production. Voltaic has been field proven for over ten years with documented output gains in real-world conditions.
